This specimen contains a beautiful, deep red-black rutile crystal with a metallic-like luster, on a rutile-pyrophyllite matrix. The large rutile crystal looks to have a couple stress fractures through the crystal, and scuffing here and there around the faces. This specimen comes with an acrylic display stand.
Rutile is an oxide mineral that is composed primarily of TiO2, although iron is a typical chemical variation. It comes in a wide variety of crystal forms, from lustrous metallic-like crystals, thin straw like crystals, to even deep red crystals with slight translucence. Rutile has also been know to form needle-like inclusion with other minerals, commonly forming with quartz. Rarer polymorphs of rutile (TiO2) include anatase and brookite, both of which have unique crystal structures.
